15 Claims.

The present invention is designed to provide rubber joints having a rubber connection between connected structures with the 'rubber adjacent to the structures so disposed to said structures as to place the rubber in shear in two directions. The invention also contemplates a rubber connection having portions at least so disposed to the members connected as to place the connecting rubber as it receives the initial thrusts on the connection out of straight line direct stress relation, preferably by U bends, across the gap formed between the members.

Preferably the supports are arranged at an angle to each other and in the carrying forward of the invention these structures may be elongated or may be united. Further features and details of the invention will appear from the specification and claims. I

In Figs. 1 and 2, l--l marks plates which are arranged in planes oifset and at an angle to each other; 2. a rubber connection bonded to the surfaces of the plates; 3 pins extending from the plates providing means for securing the plates to parts to be connected.

. Figs.3 and 4 have strips 4-4 in planes offset and at an angle to each other and rubber connections. 5 between the plates, the plates being provided with pins 6 at intervals to provide means for connecting the plates to the parts to be connected.

In Figs. 5 and 6, the plates 1, arranged at an angle to each other and having securing screws 8, are joined through angularly disposed rubber elements l0 and through the plate 9. It will be noted that the rubber elements are in shear relation to each other so that direct shear action is effected in three directions.

Figs. '1 and 8 have plates I l-l l in planes offset and at an angle to each other, a rubber member I! secured to said plates, the plates being provided with pins as securing means for securing the joint to the parts to be connected.

In the structure illustrated in Fig. 9, plates H-il are shown in parallel planes, and an S-shaped connecting rubber member connects opposite faces of said plates providing shear porcured to the plates. thus providing shear in portions of the rubber with .a movement of the plates to and from eachv other, laterally from each other. or endwis'e, and aifording very sensi tive resilient resistance in some directions through flexure of the intervening rubber.

In the structure shown in Fig. 11, there are provided two plates lll'l arranged in'i'planes' offset and at an angle to each other, and a rubin some directionsthrough vening rubben rubber member having openings ill exposing perforations,, ila in. the.plates -through .which bar member ll of U shape'conneeted to the more adiacent'faces of the plates, thus PrbVl-d-$ ing shear in portions of the rubberin several directions with relative movement of the plates.

, and receiving the initial thrusts on the connection with the connection out of straight line direct stress relation between the members.

The combination of two plates; a yielding connection between the plates including rubber or the like projecting from the faces of the plates in shear relationrelatively'tothe face of each plate and-out of direct line compression relation between'the platesfithe general direction of the portions of the connection adjacent to..the plates being out of alignment, said plates being providedwith perforations and the rubber and aifording very sensitive "resilient: resistance.

tionand the rubber member being offset at an angle to each other,.providing free shear movement in the several directions. v

Figs. 16 and 1'! illustrate a joint having plates structure, a channel is channel and extending downwardly'to below the chanel; and a ,supportingstructur'e facing upwardly, therubber members being secured to the faces of the channel and the supporting structure, the'secured portions of the rubber members in the-supporting the channel. g i

6.-The combination of a supporting member structure being offset from having spaced upwardly faced supporting'sub faces, a cushion memberof archform havingits I'd-28 arranged in planes offset and at an vangle f to each other, a rubber member 2! connecting said plates,- the rubber member being notched exposing perforations 29 in the plates, these per. forations being in substantially the same plane whereby short individual plates may be readily secured. These structures. formed in a very simple manner. provide for joint connections giving shear in three directions. 7

It will be noted that inmost of the structures the plates .are at an angle to .each other and that also in most of the structures the portions of the projections adjacent to each plate are out of alignment. The eflect of this is to sustain the major thrust of each plate on said portions in the. direction-of the planeoi' the face of the plate through shear resistance It will be noted that in these structures there is out of direct compression j relation between the plates so that the intervening rubber member ends secured to the'supporting surfaces, and a load' carryi'ng'member securedto-the' cushion member, said lead carrying member'being oflset 5 from the ends of the arch on the supporting surfaces and the cushion member between the surfaces and load carrying member being of resilient material suchasrubber. i '1. The combination of a supporting member 4o having spaced'upwardlyfaced'supporting surends of the arch on the supporting surfaces and 5 0 is a portion of the resilient rubber element which is free to respondinshear with relation to both plates and to resiliently resistthe relative movement of the membersin some directions through ilexure of the intervening portions of the rubber.
